L-Carnitine Tartrate (LCT), the stable salt of L-carnitine and tartaric acid, is a high-purity active ingredient, ideally suited for a wide range of premium nutritional and cosmetic formulations. It exists in two common stoichiometric forms, with molecular formulas of C₁₁H₁₈NO₈ (MW 292.26) and C₁₈H₃₆N₂O₁₂ (MW 472.5).

It presents as a white, crystalline powder with a characteristic acidic odor. LCT exhibits excellent solubility in water and low hygroscopicity, ensuring superior stability during storage and processing. This gives LCT a critical advantage over pure L-carnitine for solid dosage forms, guaranteeing longer shelf-life and formulation integrity for your products.

Product Features

Enhance athletic performance: L-Carnitine L-Tartrate helps increase athletes' endurance and athletic performance, especially during long-term aerobic exercise, and can effectively increase the oxidation rate of fat.

Improve fat metabolism: As an effective fat metabolism promoter, L-Carnitine L-Tartrate can help the body convert fat into energy more efficiently, helping to lose fat and maintain body shape.

Natural source: L-Carnitine L-Tartrate is derived from natural L-carnitine, and its bioavailability and solubility are improved by combining with tartaric acid.

High purity: Provides a 99% purity guarantee to ensure its high efficiency in applications such as sports nutrition and fat loss.

Product Advantages

Efficient fat burning: L-Carnitine L-Tartrate is a widely used fat burning ingredient that can effectively convert stored fat in the body into energy, suitable for weight loss and weight management.

Improve athletic endurance: Increase athletic performance, reduce muscle fatigue, and accelerate recovery, especially suitable for athletes and fitness enthusiasts.

Natural source: The product comes from the combination of natural L-carnitine and tartaric acid, with high bioavailability and high safety.

Wide range of applications: Not only used in sports nutrition and weight loss, but also in other health foods, functional beverages and other industries.

Application

1. Sports Nutrition

Athletes and fitness enthusiasts seek out ingredients that enhance fat metabolism, delay fatigue, and speed up post-exercise recovery to maintain a competitive edge.
LCT delivers superior bioavailability, with rapid absorption (peaking in ~40 mins vs. hours for pure L-carnitine), making it ideal for pre-workout formulas. LCT facilitates the transport of fatty acids into mitochondria for energy production during aerobic activity. Furthermore, clinical studies suggest LCT can reduce markers of muscle damage and oxidative stress, leading to less muscle soreness and faster recovery. This makes it the ingredient of choice for high-performance pre-workout powders, RTD drinks, and post-workout recovery blends.

2. Daily Nutrition & Wellness

Growing populations of vegetarians, vegans, and individuals with restrictive diets seek reliable sources of essential nutrients often lacking in plant-based regimens.
LCT serves as a highly stable and bioavailable daily supplement to maintain optimal metabolic function. It is perfectly suited for encapsulation or tableting in multivitamin formulas or standalone supplements, catering to health-conscious consumers, including the elderly and those with high metabolic demands.

3. Functional Foods & Pharmaceuticals

Manufacturers of solid dose formats (tablets, capsules, sachets) require ingredients that maintain potency and do not compromise product integrity, even under challenging humidity conditions.
LCT's key advantage lies in its low hygroscopicity. It provides the flexibility to create stable, high-quality solid formulations without the stickiness and degradation issues associated with pure L-carnitine. It can be seamlessly integrated into functional food bars, medical nutrition products, and dietary supplements to enhance their nutritional profile while ensuring a long shelf life.

4. Animal Nutrition

The aquaculture and livestock industries continuously seek ways to improve feed conversion rates, promote lean growth, and enhance the overall quality of farmed products.
As a feed additive, LCT promotes lipid metabolism in aquatic species and livestock. This leads to reduced body fat, increased protein deposition (lean mass), and improved growth performance. It is a valuable tool for producing healthier, higher-yield fish, shrimp, and poultry, meeting market demands for quality.

5. Cosmeceuticals

The hair care market is moving beyond basic cleansing and conditioning towards "nutri-cosmetics" that target the biology of hair growth and health.
Incorporated into premium shampoos, serums, and conditioners, LCT delivers L-carnitine directly to the hair follicle. It provides essential energy for rapidly dividing follicle cells, potentially supporting hair strength, thickness, and overall vitality. This positions your brand at the forefront of the functional hair care trend.

Q&A

Q1: What is the technical difference between L-Carnitine Tartrate and pure L-Carnitine?
A1: The primary distinction lies in pharmacokinetics and physical stability. L-Carnitine Tartrate is a salt formed for enhanced performance. It offers superior solubility and a faster absorption rate, making it the optimal choice for applications requiring rapid nutrient delivery, such as pre-workout supplements. Pure L-carnitine is more hygroscopic and less stable in solid formulations. LCT provides the lowest hygroscopicity among carnitine forms, ensuring stability during manufacturing and storage. For brands, this translates to fewer manufacturing challenges and a more consistent, higher-quality final product.

Q2: What is the recommended dosing strategy for formulators?
A2: For optimal absorption, LCT should be taken on an empty stomach to avoid competition with amino acids from dietary protein. In sports nutrition formulations, we recommend a dosage of 1-3g per serving, taken approximately 30-60 minutes pre-workout or immediately post-workout to support metabolic recovery. For general wellness products, daily doses of 500mg – 2g are common. We always advise consulting with a formulator or healthcare professional to determine the optimal dose for your specific target audience.

Q3: What is the safety profile and are there any known adverse effects?
A3: L-Carnitine Tartrate is Generally Recognized as Safe (GRAS) for use in foods and has a well-established safety profile. At recommended dosages, it is well-tolerated. In some individuals, very high doses (>5g/day) may cause mild, transient gastrointestinal discomfort (e.g., nausea, diarrhea) or a temporary fishy body odor, which is due to microbial metabolism in the gut. These effects are reversible upon dosage reduction.

Q4: Are there any contraindications for specific populations?
A4: While safe for healthy adults and children, LCT supplementation is not recommended for individuals with a history of seizure disorders or those undergoing dialysis. Pregnant or lactating women and individuals taking anticoagulant or thyroid medications should consult their physician before use. It is also contraindicated for individuals with liver or kidney impairment.

Q5: What are the storage and handling recommendations for this raw material?
A5: To maintain its excellent stability, LCT should be stored in a tightly sealed, original container in a cool, dry, and well-ventilated area, protected from direct sunlight and moisture. Under these conditions, the product retains its specification and potency for an extended period, well beyond the standard shelf life.

Q6: Where can I source high-quality, certified L-Carnitine Tartrate for my products?
